What it does
AceTagGen helps people write better prompts for Suno, the music generator. It is an independent tool and says it is not affiliated with Suno. A free 12-step tag builder walks through genre, mood, instruments, vocals, tempo and key, with a live character counter, conflict warnings and a 100-point quality score before you paste the result into Suno. A Song Editor places bracket tags line by line in the lyrics, and a built-in AI lyrics writer works in 12 languages. A paid option called AceTagGen AI takes a plain-language description of a song and returns a Style, Lyrics and tag set; the site lists it at $7 per month for 300 requests. The scoring code is published as an npm package under the MIT licence and is also reachable through a public REST API. The site says the free tools need no signup and that it carries no ads or trackers.
